Application filed March 21, 1928.

The present invention relates te bumpers for automobiles and the like;and its object is to provide an impact-receiving bumper bar having amiddle portion projecting trom the `inain portion of itsimpact-receiving tace and extending in concavel t inclined opposite cirecticns toward the ends of the bar7 thus providing improved means fordede-Sting the direct thrust ot an impacting body inclinedly tov-Jardone or the other ot said ends; and further; to provide a.forwardly-projecting element mounted on an impact-receiving bar andhaving opposite sides extending inclinedly toward the ends respectivelyof the bar,

" and tor the like purpose; a further obj ect being to provide improvedmeans for connect- 'ng a plurarity ot suoli bars disposed a vericalplane.

These and any other and more specific objects hereinafter appearing areattained by, and the invention tinds preferable embodiment in; thebumper structureV hereinafter particularlyv described in the body ofthis speciication and illustrated by the accompanying drawings, inwhich:

Figure 1 is a top pla-n VView of a bumper for automobiles;

Figure 2 is a trent 'iew thereof;

Figure 3 is a sectional view ot the same taken on vertical planescorresponding' to line 9,--3 ot Figure 5;

Figure 5iis a vertical sectional view et certain parts oi the structuretaken on line fl-Li et Figure 2;

Figure 5 is a horizontal sectional view ot certain part-s of thestructure taken on line ot' Figure and Figure@ is a rear view ot an endot the bumper bars with connected parts.

In the embodiment of the invention illustrated by these drawings; abumper ior vehicles is shown having a plurality (three in thisconstruction) ot' impact-receiving, preferably resilient, bars 1extending horizontally and parallelly and disposed in a Vertical plane.The ends ot these bars are connected by means of a vertical pintle 2with a rear bar 3 which is supported by the bracket 4 on the vehiclesframe 5. The 'front or impact-receiving face VG of each of the bars 1urves concat-'ely at 7, 7 toward a point intermediate the ends of thebar7 i. e.; the middle of the bar, as seen in Figure 5; that is; thefront face of the bar sei-iai no. ecaasc.

mentation et such ettect) an element 9 may be mounted on the middles ofthe bars; projecting outwardly or forwardly from their impact-receivine`faces as particularly shown in Figure This element 9 has the oppositesides 10; 10 extending inclinedly to the bars said tace.

The purpose or etect ot thus shaping the bar 1 itself or the attachedelement 9 is to delect an impacting body from its direct forward thrustadjacent the middle of the bars and Cause it to strike the inclinedgortion T of the bar; or; in case the element 9 be provided, to strikethe inclined side 10 ot' said element and slide along said por-ion 7 orside 10 the case may be, thus lessening the torce ot' such an impact.

The bars 1 are connected by clamping elements in their middles andadjacent their ends. rlhe middle clamping element comprises a pair otmembers-the aforementioned part 9 and the member 12 engaging theopposite sides of the bars 1. One of said clamp members-the part 9-hasvertically extending slots 13 adapted to receive the shanks of bolts 14and retain the heads .15 ot these bolts. Nuts 1Y are threaded on thesebolts7 and being .screwed down on the rear member l2, serve to clamp themembers S) and 12 together with the bars 1 between them.

The other clamping elements (adjacent the ends of said bars) areconstructed similarly to the clamping e ement above described, havingforward members 91, provided with slots 181, rea` members 121; 122,bolts 1&1 having heads 151 holdingly received in said slots; and nuts1G1 threaded on the bolts for clamping the parts together.

The invention being intended to be pointed out in the claims, is not tobe limited to or by details of construction of the particularenibodiment thereof illustrated by the drawings or hereinbeforedescribed.

claim:

1. In a bumper for vehicles: a horizontally extending one-piece barcomprising a middle portion and lateral portion having impact-receivingfaces extending in continuously and middle portion, the impact-receivingface of leach of saidlateral portions, at any Vertical section thereof,being in a vertical plane.

2. In a. bumper for vehicles: an impact bar; an element mounted thereon,projecting torwardly from the bars impact-receiving face and havingimpact-receiving sides, outwardly-concave portions of which are inclinedto the bars said face.

3. n a bumper for vehicles z an impact bar; an element detaohablymounted thereon, projecting forwardly from the bars impact-receivingface and having impact-receiving sides, outwardly-concave portions ofwhich lare inclined to the bai-s said face.

l-. In a bumper for vehicles: a plurality of impact bars disposed in avertical plane; a connecting element therefor comprising a pair ofmembers engaging the bars opposite sides; a threaded bolt extendingbetween said. members and carrying a nut to clamp said members togetherWith the bars between them; one of said members having a slot adapted toreceive the shank of said bolt and toretain its Y head, and the forwardone of Said members
